Answer:
x = ±1
Step-by-step explanation:
Step 1: Define variables
f(x) = x² + 1
f(x) = 2
Step 2: Substitute
2 = x² + 1
Step 3: Solve for <em>x</em>
0 = x² - 1
0 = (x - 1)(x + 1)
x - 1 = 0
x = 1
x + 1 = 0
x = -1
∴ x = ±1
Answer:
p(F)=0.73
Step-by-step explanation:
we have by identity

Thus for given events E and F
we have
Applying values we get

Thus
p(F) = 0.82+0.09-0.18
p(F) = 0.73
